WORKER - Anterior clypeal margin with a weakly arcuate impression; clypeus with sharp lateral carinae; antenna 12-segmented; mandibles with four teeth apparent, and weak basal striations; frontal lobes set quite far apart; moderate eyes (0.22 X HW, with 9-10 ommatidia in the longest row; mesonotal groove a well-marked and slghtly impressed suture and cross-ribbing, propodeum dorsum ca 2 X longer than the declivity, propodeal spiracle small and circular; petiole with a very short pedicel, in profile the node as high as the level of the propodeum dorsum and round pyramidal at the apex; postpetiole almost 2X width of petiole, from above spherical; erect hairs sparse but present on all dorsum except the propodeum; anterior margin of clypeus with six long down curved hairs, underside of head with long hairs almost forming a psammophore; sculpturation reduced to almost nil on the head and alitrunk, very faint spiculation of lateral propodeum, head with distinctive small hair pits, whole body shiny; colour near uniform yellow brown but head and gaster darker.
TL ca 2.2 mm; HL 0.58, HW 0.52, CI 97, SL 0.47, SI 65, PW 0.28; palp formula unobservable.
Without clear relatives - near unique characters appear to be the shape of the head, widest at the posterior of the eyes but with the anterior margin about 30% wider than the occiput; and, the long hairs on the underside of the head. Possibly falls in the monomorium-group of Bolton (1987). Bolton's key leads to couplet 97, the thread then breaks down as this has short scapes, SI 65. Ignoring that also leads nowhere.
